To n.71', whoml it may concern: l

selten', Swansea, England, have invented. Dew or Improved Pneumatic-Tiro Pressure- Gage, (for which I have obtained a provisional British patent, No. l0.378,dated May17:1899,) of whichthe following is a. specification.

This invention relates to a simple apparu- Lns by which a leuk or diminution 0f pressure in a puenmn'ticti re can be readily determined; und lhe'invention resides in. t-henovel feuturee of construcion ser foiih in the following specification and claims and: illustlrut-ed iu the annexed druvingr,V in which- Figure l shows u. foce elevation of the epparnbus applied to n tire, the latter beine Seciimml. Figi is 'aview like Fig. l, Lhe case or cylinder being removed to exposelhe cnntuined mechanism. Fig. 2 is a deml. Fig.'

In the drawings is shown a cylindrical boxV or case, comprising the wall or shell A, with the covers (l and C' closing the ends` of the shell, Lhelutirr l .Irving u slot. or opening,r B und scnlesJnt. opposite `sides of the slol..l A sleur l) extends through or is guided by the covers und hasfali'one end a shoe E,\vl1ich can lurn or swivel on the stem, so that `the elem and shoe are rotary with respect to one. another. Slipped ont' stem D und ,supported` by cover C' is u stay o. support J', as seen in' Fig. 2. The stein D is wrcwdhreuded, and to this stem is screwed :l nut F', a grooved disk F being screwed to or seated about. the siem above this nut. VInto the groove of this disk aresli pped the branches of `the fork G., (shown in dert-nil at. Fig. 2,) thisvfork carryl in Lr a pointer H at'. one of the scales on shell A. Screwed or secured to the stein is also n. disk I, which Vcorrieri a second pointer Jfor the seoonducnle.' The spring L, seated about pressd between diskv I and hell-jcover C. To. the top of the stem are screwed a nui, R'and. finger button 0r handle Q, which is locked hy the stem und enable the lett-'erin he turned by the handle Q.; When the spring: L is free .m press pointers JH iu the direction aw'ay from eover C, the nut F comes to rest on botorlevs J'. The ointerHisthus revenbed e l P.

fom cover C' and disk I comes to on brace i from stri-king against; or bein-g'bent or dis- 55 torted by the lower boundary ory terininntion of slot B.

Secured tocovex-C is nstrap or metal band M, having* buttons O O'. A lstrap P has a series t. eyes which can be slipped onto the lugs 6o or buttons-0 O', so as' to form the strap? into a loopof greater or less diameter, as required.

The manner of using thedevice is simple and readily 'understood 'Say that. the rider has t-he tire inflated to the required pressure. 65l

The shoe E. is placed against t-he tire and the shell A pressed toward the tire to ompress spring I. und the s'tmp P looped about the tire or felly und secured to buttons OU'. Note is .new token oiihepointawhirh eithorqininier go Il or .Islands-us, fo'. example, note is made of the pointer Jrst-nndi'ni.r at number 200n its s cnle. 'l'he onge is now dismounted or put asideand the vehicle is put. in use.- After a certain run or lapse of time the'gage is re -75 applied, as before', und if the pointerJ is then again at. 20 ily shown that no leuk or della tion of the tire has occurred; contrariwise if the pointer J non stands at., say, 15 or` if pointer H should have shifted, f or example, 8o

from 0 tu 1.

The scale of poinie'r H, it is noted, is num- 4 i bored consecutively, a's 0, 1, 2, and so on, while the scale of pointer J runs by fives. seen fit; but thel numberings shown have been [ouml convenient, in practice.

In the device shown i n the drawings the dnphcate pointers und leales were used together u1 the snme'time, the upper or right-hand 9o scale was arranged or graduated to indicate pounds per sourire inch, and' the othexisonlel i represented parts of 'an inch.'

What I claim as new, and desire to secureA 'I by Leiters'Puieut., is--A- .l 1.-*A gage for indicating pressure in pneu- ,lnutic tires said gage comprising a slotted ense or shell having covers C C' and seules an the slot., a sliding spring-pressed stem extended Lhrough the covers and having a shoe to sitme against the tire and poiniers bo travel along Lhe scales, aud lugs or buttons for securingav strap about tha-l tire to hold the shoe in .com met. with'such ti re, substantially as described.

These arrangements can he varied ifV $5 a strap about the mir .o liold the shoe. in. con-k racL with such tire, sulisfantially as described.'

3. A blotted case orf shell and a screw-sten; mid evdby or slidahle through the cms-e, a shoe on the stem, a pointexerryi'ng' gmoved disk F and a second p0int eicarrying disk I on the stem; a mit F and brace J' for the disks, a ,mi-infr ma'de to press against disk l no mov tho stein, and astrnp and -lnop M I fof ilie case, substantially as (lesurihed. ,1 l

4. A slotted caso or cylinder A liz/wing n scale und covers CCH a screw-*stem Dguided zo through lne'covers, n loose or swiveling shoe' at. the bottom of the stem, pointr-carrying. disks F I on the stein', a spring' L `braced ive- Lween a disk and a cover, a strap M`secnred to the eae, a srs-ap? adapted. to be loopPd -or secured'tothe first-named strap, a handlef nut Q on the stem, and a lock oijam punk foi'the handle-nur., substantially as described.
